The numbers it puts down are incredible, the results are impressive.

What is even more impressive is that fact that the Redline Motorsports dyno measured 455 rear wheel horsepower and 420lb-ft of rear wheel torque. When you consider the advertised numbers of 505 horsepower and 481lb-ft of torque, the Z/28 is surprisingly efficient in putting the power to the ground.
